Hercules Renewal'd Pin Code
Feature is not, I repeat, NOT complete. the decryption is not fully functional which leads to dial values different from the ones the player used. Credits: lemongrass3110 for the base yommy for the packets LightFighter for the decrypt function (altho its not stable :P) Signed-off-by: shennetsind <ind@henn.et>
